17. Terebratula [Waldheimia) sqjtigera, Loven, Index Moll. 

 Scand. p. 29. 



Hab. Norway, Finmark. 



Another Scandinavian species, recently described by Loven, 

 of a more oblong form than T, cranium, more concavely depressed 

 towards the anterior margin, and possibly distinct ; but the spe- 

 cies needs further research. 



Subgenus 4. Terebratella, D^Orbigny. 

 Apophysis a freely produced riband-like reflected loop, resembling 

 that ©/"Waldheimia, attached towards the middle by a cross 

 process affixed to a central septum.

Anomia striata Magellanica, Chemnitz. 



dorsata, Gmelin. 



Terebratula dorsata, Lamarck. 



Sowerbyi, King. 



Chilensis, Broderip. 



Delthyris dorsata, Menke. 



Terebratella dorsata, Davidson, 



Hab. Straits of Magellan ; King. Valparaiso ; Cuming. 

 I include Mr. Broderip^s T. Chilensis with Gmelin's A. dorsata, 

 as well as T. Sowerbyi and fleonwsa of Capt. King, already re- 

 ferred to it by Professor Suess ; and I restore to the species the 

 prior and very characteristic name of Magellanica given to it 

 by Chemnitz. 



19. Terebratula {Terebratella) transversa, Sowerby, Thes. Conch, 

 i. p. 361, pi. 72. f. 114, 115 ; Conch. Icon. pi. 5. f. 22. 

 Hab. ? 



This shell (kindly transmitted to me by Mr. Norris, nephew 

 of the late owner of it), which I have examined with much care, 

 is intermediate between certain varieties of the very variable 

 T. Magellanica and T. Bouchardii. I have not seen the second 

 specimen of it, referred to by Mr. Sowerby as being in the col- 

 lection of M. Janelle, and still leave the species in doubt. 



20. Terebratula {Terebratella) Bouchardii, Davidson, Ann. and 

 Mag. Nat. Hist. 1852, ix. p. 367; Proc.Zool.Soc. pi. 14. f. 4-6; 

 Conch. Icon. pi. 5. f. 17. 



Hab. ? 



This is another species founded on a single specimen of some- 

 what doubtful specific character.
